The save_cpu_target functions should take "u32 __iomem *", not a plain "u32 *" as it is passed to register access functions. Fix the following warnings by adding the annotation: drivers/bus/mvebu-mbus.c:739:17: warning: incorrect type in argument 2 (different address spaces) drivers/bus/mvebu-mbus.c:739:17: expected void volatile [noderef] <asn:2>*addr drivers/bus/mvebu-mbus.c:739:17: got unsigned int [usertype] * drivers/bus/mvebu-mbus.c:741:17: warning: incorrect type in argument 2 (different address spaces) drivers/bus/mvebu-mbus.c:741:17: expected void volatile [noderef] <asn:2>*addr drivers/bus/mvebu-mbus.c:741:17: got unsigned int [usertype] * drivers/bus/mvebu-mbus.c:742:17: warning: incorrect type in argument 2 (different address spaces) drivers/bus/mvebu-mbus.c:742:17: expected void volatile [noderef] <asn:2>*addr drivers/bus/mvebu-mbus.c:742:17: got unsigned int [usertype] * drivers/bus/mvebu-mbus.c:744:17: warning: incorrect type in argument 2 (different address spaces) drivers/bus/mvebu-mbus.c:744:17: expected void volatile [noderef] <asn:2>*addr drivers/bus/mvebu-mbus.c:744:17: got unsigned int [usertype] * drivers/bus/mvebu-mbus.c:790:17: warning: incorrect type in argument 2 (different address spaces) drivers/bus/mvebu-mbus.c:790:17: expected void volatile [noderef] <asn:2>*addr drivers/bus/mvebu-mbus.c:790:17: got unsigned int [usertype] * drivers/bus/mvebu-mbus.c:792:17: warning: incorrect type in argument 2 (different address spaces) drivers/bus/mvebu-mbus.c:792:17: expected void volatile [noderef] <asn:2>*addr drivers/bus/mvebu-mbus.c:792:17: got unsigned int [usertype] * Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com>
